This work reports on the successful production of poly(ethylene furanoate) (PEF) thin films and a comparison of the enzymatic hydrolysis of PEF and poly(ethylene terephthalate) (PET) films with three different crystallinities (0, 10 and 20%). The data suggest that the PEF films are enzymatically hydrolyzed 1.7 times faster than the commonly investigated PET films. QCM-D and SEM/AFM analyses fully confirm the observed reaction trend. The results also show a negative dependence of the hydrolysis rates with the increasing of the film crystallinity.

各种结晶度的呋喃甲酸乙烯酯薄膜的酶促表面水解

这项工作报告了成功生产聚呋喃乙烯酸酯(PEF)薄膜的过程,并比较了PEF和具有三种不同结晶度(0%,10%和20%)的聚对苯二甲酸乙二醇酯(PET)薄膜的酶水解作用。数据表明,PEF膜的酶水解速度比通常研究的PET膜快1.7倍。QCM-D和SEM / AFM分析完全证实了观察到的反应趋势。结果还显示水解速率随膜结晶度的增加而呈负相关。
